YARN' CLEANER.

Application filed January 3, 1924. Serial No. 684,131,

To (ZZ w70m 25 7na 7 concern Be it known that I, LOUIS B. HAS- n.uono1:, a citrzen of the United States, re-

siding at Elmira, in the county of Chemung and State of New York, have invented certain new and useful Improvements in Yarn Cleaners, fully described and represented in the following speoification and the accompanying drawing, forming a 'part of the same.

This invention relates to yarn cleaners and aims to provide a simple and effective device for removing impurities of all sorts from a traveling yarn.

An object of the invention is to provide a yarn cleaner in which all im urities removed from the yarn and any brous mat ter dctached with them are continuously discharged from the cleaner without the use of any mechanically-driven parts. A further object is to provide a yarn Cleaner which will place the yarn under any desired tension so that no tension device need be used with the cleaner. A still further object is to provide a cleaner which will automatically adjust itself for operation upon a yarn of any size.

I have found that if a yarn be drawn across a scraping edge and held in firm contact with said edge by a member opposed to the edge and either urged toward the edge or separated from it by a distance less than the normal diameter of the yarn, the scraping action of the edge is effective to remove small specks and particles adhering to the yarn as well as larger impurities. While slub catchers in which the yarn is drawn between two opposed edges have long been in use, it has heretofore proved impossible to obtain an effective scraping action from such edges without removing fibrous matter from the yarn which winds around the yarn in front of the edges, becomes reattached to the yarn, and forms slubs which cause the yarn to break in its passage through the cleaner. By the present invention I have overcome this difliculty and have produced a practical cleaner in which the yarn is effectively scraped without the danger of such balling up.7

In accordance with the invention, either the member providing the scraping edge or the opposed member which holds the yarn in contact with this edge is given a continuous movement in a direction longitudinal of '-but is discharged continuously from the cleaner with the particles which are de tached from the yarn. In the form of the invention which I consider best, the yarn is drawn across the scraping edge in a direction oblique thereto so that the longitudinal movement of one of the members may be caused by the friction of the yarn against it. In this way the necessity of mechani cally-driven parts is avoided.

In order to provide the most effective 'scraping, both of the members between which the yarn is drawn may be provided with scraping edges. Thus, a yarn cleaner embodying the invention may be provided with a fixed arcuate blade and with a cylindrical blade which is rotatably mounted .and positioned so that a portion of its edge is always opposed to and parallel with the edge of the fixed blade. The yarn is drawn between the opposed edges, and the blades are yieldably urged toward each other so that the yarn contacts firmly with each edge.

The yain is guided to cross the edges in an oblique direction so that the cylindrical bladeis continuously rotated by the friction of the yarn traveling obliquely across its edge. This rotation of the blade causes a continuous longitudinal movement of its scraping edge which carries away all particles and fibrous matter scraped from the yarn by the two edges.

In"order that the invention may clearly be understood, I will describe in detail the specific yarn cleaher embodying it which is shown in the accompanying drawing, in which Fig. 1 is a view of the cleaner looking in the direction of the arrow 1 in Fig. 3;

' Fig. 2 is a view of the cleaner looking in the direction of the arrow 2 in Fig. 3;

Fig. 3 is an enlarged transverse section of the cleaner taken on the line 33 of Fig. 1; and

Fig. '4l is a longitudinal section of the clea1ier taken on the line 44 of Fig. 2.

The cleaner illustrated has a supporting plate 10 on which are mounted a plurality of cleaning units 11, 12, 13 and 14, each of a mov-able scraping edge. r The plate 10 has a flange to which is secured a supporting bracket 16. i In order that the plate 10 may be tipped laterally at any desire-d angl" to the horizontal, the bracket 16 is provided with a pin 18 prjecting at one end of the plate 10 and adjustably secured by means of a set screw 19 in a socket 20 at the outer end of a supporting arm 21. A traveling yarn A. is guided across the plate 10 in a longitudinal direction by a front guide 22 and a rear guide 23. In its travel across the plate 10 the yarn A *passesbetween the scraping edges of each of the units.

As the cleaning units are alike, a description of one of them will suffice. The unit 11 has afixed arcuate scraping ade which is curved so as to lie in a cylindrically curved surface whose axis is perpendicular to the plate 10. The blade 30 has at its inner edge an external flange 31 which is at tached to the plate 10 by means of screws 32, along the periphery of a semi-circular recess in the plate. The blade 30 is bevelled at 34 on its convex surface so that its outer edge 35 is sharp. This edge 35 which has the form of an are of a circle constitutes the fixed scraping edge of the unit.

By reference to Fig. 4 it will be seen that the position of the blade 30 on the plate 10 is such that a yarn traveling in a straight line from the front guide 22 to the rear guide 23 passes across its scraping edge 35 in an oblique direction, and that particles projecting from the yarn are brought into contact with the concave side of the blade 30.

The movable scraping blade of the unit 11 has the form of a cylindrical flange clepending from a disc 41. The blade 40 and the disc 41 together form an inverted cup shaped member which has a hollow upwardly extending axial sleeve 42 rotatably mounted on a depending pin 43 secured in the outer end of a bracket 44 which may be formed integral with the plate 10. The pin 43 is co-axial with the fixed blade 30. The sleeve 42 provides a long bearing against the pin 43, preventing the cup-shaped member 40. 41 from tilting. The lower end of the pin 43 projects onlv a small distance below the disc 41 so that fibrous matter scraped from the varn does not catch on this mav be varied by slidin.q the axial extenson 42 along the pin 43. The edge 46 is norma ll v urged toward the edge by the werght of thecupshaped member49, 41.

Behind the fixed blade 30 of the unit 11 is a pin 50 whose upper surface is located so as to guide the yarn A in a straight line from the front guide 29 toward the rear guide 23. 7

The other units are like the unit 11 which has been described. except that there is no guiding pin behind the rear unit 14, 'as the rear guide 98 is close to this unit.

The operation of the cleaner which has been described, is as follows:The device is threaded by dropping a yarn into the recesses of the front and rear guides 22, As soon as apull is applied to the yarn to draw it forward through the cleaner, the yarn is brought against the bevelled edges 34 and ot each unit and raises the cupshaped members 40, 41 of each unit sufficiently to enable the yarn to enter between the scraping edges 35 and 46. The path of the yarn is best shown in Figs. l and 4 where it will be seen that the yarn passes between the scraping edges of each unit at a point B crossing each edge obliquely at this point. As the scraping edges are urged together by the weight of the cup-shaped 1nemben both of them contact lirmly with the varn at the point B. Since the varn les along a chord of the circle in which the movable edge 46 lies it touches this edge at another point C. The point C is. however. in front of the front end of the fixed blade 30 and in consequence the yarn is not pressed against the edge 46 at this p int. and substantially no fibrous matter is removed from it until it passes between the two edges at the point B. At this point an particles or irregularit-ies projecting from the varn eneounter the coneave surfaces of the fixed and movable blades 30, 40. The resu t is that i*t' an v such particles catch on the edges ot the blades the varn is deflected 'lmvmvar ll from its course 0t' travel. The pins 50. and the rear guide 23, however. 'uevout the varn from moving laterall Far mour:h to lose contact with the Ii::! l edges 35 ot auv of the units. The slight lateral movement g ven to the vara in this manner as it erosses between the edges makes the srraping action of the edges more ettective.

The fr ction between the varn and the edge 46 of each unit causes a eontmuous longitudinal movement of each edge 46 which is permitted bv rotatiou of each cupshaped member 40. 41 about its supporting pin 43. As the varn passes between the seraping edges of the units. impurities of all sorts are scraped From ita The impurities removed bv the edges ot each unit, and all fibrous matter which mav be removed from the varn with them. follow the longitudinal movement of the scraping edge 46 of that unit. Some of the particles fall from the seraping edges 46 as soon as they are free from the yarn. The recesses 33 in the plate the cleaner. Other particles and some fibrous matter are rolled along between the edges s"'-6 and 35 until they reach the rear end of the blade 30 where they fall from the cleaner. All particles and any iibrous matter scraped from the yarn are, therefore, eontinuously discharged irom the cleaner,

The ihanness ot the contact of the scraping edges with the yarn and the tension applied to the yarn may be regulated either by changing the angie of the plate 10 to the horizontal or by varying the number of weight discs 51 placed on top of the disk L1 of each unit. In this manner the pressure en the yarn is adjusted so that the edges contact with the yarn as iirmly as possible without placing the yarn under suflicient teusion to cause it to break.

Many changes may be made in the form and arrangemeut of the parts of the specific ombodiment illustrated without departing from my invention. I wish it understood, therefore, that the invention is not oonfined to particular features of the embodiment shown, except in so far as is specified in the claims which follow.
